MATLAB: Hi guys I need help for the final project, Im trying to create a gui that calculates the moment of inertia for different shapes. I ve tried the best please help

Question

function varargout = Momen_calculator(varargin)
% MOMEN_CALCULATOR MATLAB code for Momen_calculator.fig
%      MOMEN_CALCULATOR, by itself, creates a new MOMEN_CALCULATOR or raises the existing
%      singleton*.
%


%      H = MOMEN_CALCULATOR returns the handle to a new MOMEN_CALCULATOR or the handle to
%      the existing singleton*.
%
%      MOMEN_CALCULATOR('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in MOMEN_CALCULATOR.M with the given input arguments.
%
%      MOMEN_CALCULATOR('Property','Value',...) creates a new MOMEN_CALCULATOR or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Momen_calculator_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Momen_calculator_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
